It’s good that Yahoo! provides everyone a hint that some change is brewing over its search algorithms.

But that’s about it. Every single update posted on its Yahoo! Search blog about the ‘weather report’, loosely referring to Yahoo’s search index update, will mention a generic paragraph. Just like the latest update dated 7th of April 2009:

We’ll be rolling out some changes to our crawling, indexing and ranking algorithms over the next few days and expect the update will be completed soon. As you know, throughout this process you may see some ranking changes and page shuffling in the index.

That’s the same as the Feb 27th and Nov 21st 2008 updates. Sorry folks, that’s how far Yahoo! will share. At least it makes confirmation, unlike Google.
